MANIFOLDISTG REGISTER.

Application filed February 7, 1921.

To all whom it may concern:

Be it known that I, JOHN Q. SHERMAN, a citizen of the United States, and a resident of the city of Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Manifolding Registers, of which the following is a full, clear, and exact description, reference being had to the drawings forming part of this specification.

y invention relates to devices for feeding a plurality of superimposed strips or webs of paper in true alignment, for purposes of forming like impressions on the webs while in' superimposed position. Ma-- chines of this character include autographio registers, flat bed typewriting manifolding machines, and manifolding typewriters of various kinds to all of which machines my invention is applicable.

The object of my invention is to provide a form of pin feed for paper, whereby a pin will enter aligned apertures therein and move through a path whilein engagement therewith, which embodies not only a. movement to draw the paper through a straight path, but also a lengthwise movement with relation to the paper so as to accomplish a thrusting motion in entering the said apertures.

The usual type of pin feed mechanism series of pins mounted on a rotary member, and moving around, so as to bring the pins into the paper at the upper end of the circular movement together with some means for preserving a path for the paper that is substantially tangential to the said rotary member. As can be readily fl5served, the chance for defective operation in such a feed arises. in cases where the rotary bodies are of such size or the pin spacing or path of the paper such as to bring a number of pins into contact with the paper at the same time, with the resulting tendency of the entering and departing pins tearing out the edges of the apertures.

By means of my present invention, the advantages of the pin feed in the various kinds of machines mentioned, are preserved, while by imparting a thrust and retraction to the pins, I may accomplish a quick full engagement, and a complete Withdirawal without mutilation. Also, the necessity of carefully guarding the path of the paper is somewhat obviated, because the dangers in Serial No. 443,009.

departure from a not evident.

The above objects and other advantages to be noted, I accomplish by that certain construction and arrangement of parts to be hereinafter more specifically pointed out and claimed.

In the drawings Figure l is a side elevation, partly broken away of a rotary feed pin device, constructed according to my invention.

Figure 2 is a front elevation, showing a detail of a feed shaft and feed pin device, of the type illustrated in Figure 1.

Figure 3 is a detail side elevation showing a form of composite pressure roll and feed pin mechanismf Figure 4 is a front elevation, showing in detail the parts illustrated in Figure 3.

Figure 5 is a perspective detail, showin the feed pin device, as employed with a sliding bar feed for paper.

igure 6 is a front elevation partly in section, showing the same parts illustrated in Figure 5 with the addition of the feed shaft, and rack and pinion device for moving the sliding bar.

Figure 7 is a detail plan view, with a partial elevation developed therefrom, illustrating the extensible roller guide and switch, which controls the idle return of the pins in the sliding bar type of feed. F igure 8 is a detail section of a spring return device for the parts shown in Figures 5-7.

It will be noted above, that I have shown several types of feeds, in each of which the longitudinally moving pin is shown, and in each of which the pin moves in a path to feed the pap r. In each instance, also, a fixed cam is employed for the purpose of imparting the longitudinal movement to the pin, although this is not intended as illustrating the only possible method which occurs to me of accomplishing this movement. Neither do I, because of the showing of various modifications, intend to carry the meaning that no other uses of modifications occur to me, for my invention.

Referring first to the forms shown in Figures 1 to 4 of the drawings, I wish to that there are two types of feed shown therein, both. of which are applicable to manifolding machines having a fiat writing table or bed, or having a rotary platen, against which the writing is done.

In Figures 1 and 2, the feed shaft is true tangential path are note I shown at 1, having a handle 2, which carries a disk 3. This disk has a rib 4, along an inner edge of the periphery which is perforated with holes for the feed pins 5. Mounted against the side of the disk are a set of plates 6, making up an annular flange which is also perforated for the pins, said pins lying between the rib and flange member, and having springs 7 coiled around them. The springs tend to keep the pins in a position with their ends retracted to within the bounds of the periphery of the disk.

Held on a bar 8 which is mounted transversely of the disk, is a cam 9, of the desired shape, which lies within the'sp-ace outlined by the rib and flange member, and against which. the ends of the pins will bear, thereby thrusting them out through the rib, into a osition for paper engagement.

hile no specific machine is shown in connection with Figures 1 and 2, it will be understood that one or more of these feed pin devices may be mounted on a feed shaft or platen, and that preferably a rib 10 will be formed along-side of the pins to serve the function of keeping away from a binding contact with the periphery of the disk or disks, such pressure member as is used for keeping the paper down on the pins.

In operating such a device when mounted in a manifolding machine or typewriter, the operator sets the paper, with its holes down over the pins, all webs aligned as do sired, and then turns the feed shaft, which will give a thrust and withdrawal to the pins, and also a motion through a feed arc. The shape of the cam, as has been said, is a, matter of preference, dependent upon the nature of feed desired.

Turning to Figures 3 and 4, it will be noted that in this case I have shown a roll or platen 11', operated by a shaft 12, which roll or platen works against a pressure roll 13, held on small bell cranks 14. Also on the shaft is a cam 15, which operates with the feed shaft to raise up the roll 13 at the time of feed pin engagement.

The feed pin is carried by the rib 17 at the end or ends of the roll or platen, there being in this case but one feed pin in each rib portion. The pin has an enlarged head 1 8 and a shank 19, and the hole 16 in the rib is too small at the base for passage of the head, thereby doing away with the flange member of the first modification. The spring 20 encompassing the pin bears against the base of the hole in the rib and islfsecured at its other end to the pin itse An arm 21 carries the cam piece 22 against which the pin finds a bearing during its path with the platen, this period of contact corresponding with the position of the cam 15.

To impart spring pressure to the roll 13,

I mount in a small guide 23, suitably supported in fixed position relative to the machine, a sliding piece 24, which is under the influence of a spring 25 dropped into the guide and held there by a screw plug 26. A finger 27 is pivoted to the guide piece and may be used to throw up the sliding piece.

The sliding piece bears against the bell crank 14, and thus presses the roll down against the platen. Where the mounting devices for the roll 13 are rigid and non-bendable, it will not be necessary to duplicate this spring structure for both ends of the roll. To hold the roll in raised position, a finger 28 may be provided which engages behind a notch in the bell crank when the roll is raised.

The device now described operates as follows: after the operator has mounted the paper in the machine and set it with its alignment holes over the pin, or pins, should the pin feature be duplicated for both ends of the roll or platen, he turns the handle on the roll or platen shaft, which acts to move 'the pin and feed the paper between the platen and the pressure roll 13. When the pin comes uppermost it will be thrust longitudlnally into engagement with the next aperture in the paper, and at the same time the upper roll 13 will be raised by the cam. The feed pin will then move around on the shaft as a center, drawing the paper along with it, and aligning the forms on the various superimposed webs, said webs being free to slide on each other, and thus adjust themselves on the pin.

This feed pin operation will continue for a short space after which the pin will be sharply retracted from the paper, because of the lower end of the pin sliding off the cam. The timing of the feed pin operation with reference to the balance of the feed may be as desired. The slot 13,in the roller 13 gives pin clearance at all times.

In the modification shown in Figures 5, 6 and 7, I show a manifolder having a flat bed or writing table 40, beneath which are a pair of guides 41 extending lengthwise of the bed, and mounting slidably the bars 42.

But one set of these bars are shown, but it.

will be understood that they may be duplicated or not as desired. The bar has a rack 43 on its under side, and the feed shaft 44 has a pinion 45 which engages the rack.

Within this sliding bar or bars are formed suitable holes 46 for a series of interspaced pins 47, these pins being fitted with springs 48, within the holes, and held a ainst falling out by strips 49 closing the hoFes except for suflicient clearance for the shank of the pins. Mounted on a rooved bracket 50 at one side of the machlne is a sliding frame 51, which carries a cam 52, against which the pins bear which are carried in the bar.

Thus at a desired point in the machine,

the movement of the sliding bar will result in the pins being forced up above the level of the writing table, with which the bar is flush, thereby causing them to engage in suitably formed alignment apertures in the paper to be fed. The pins will also have a path of movement with the bar, so as to feed the paper, while maintaining a vertical position at all times.

pressure roll 53 is mounted over the writing table at the feeding point and normally rests on a plate 54 mounted against the outside of the sliding bar, so as to remain in a position out of clamping contact with the paper while it is being fed. A reduced end 55 to the plate permits the roll to fall when the sliding bar is entirely retracted and during its forward motion, the plate rides on a roller 56, which said roller is mounted on the sliding frame 51, above referred to. The plate 54 is mounted on the bar by screws 54 having sleeves that engage in slots 54", so that the roller 56 is enabled to accurately position the said plate.

The frame 51 is shifted laterally to permit the bar to return without the pins bein thrust above the level ofthe writing table or platen. To accomplish this, there is mounted on an arm 57, a roller 58, which during the motion of the sliding bar, rides against a switching device on the under side of the said bar. The arm 57 is on the sliding frame 51 and a spring 59 engaging between the sliding frame and the wall of the machine, keeps the said roller against the switching device.

As a switching device I employ a pair of plates 60, 61, which have a cut-away por tion at 62, to permit of an overlap for adjusting length of feed. The piece 61 is secured in permanent positlon on the under side of the bar and the piece is adjustably mounted on screws 63, engaging in a slot 64 in the piece. Extra screw holes as at 65 may also be provided and it may be observed that I thereby provide an extensible rib or bar against which the roller 58 will ride.

At the end of the ,piece 61 it is equipped with a swinging arm 66, pivoted at 67 and provided with a spring 68, which normally keeps this arm 66 up against a diverting plate 69.

The structure operates as follows: movement of the main slide bar will bring the pins seriatim up through the holes in the paper at the feeding point, the cam device being held in position to act on the pins during this motion, by the roller 58 riding against the switching device. As the sliding bar reaches the forward end of its stroke, dependent upon the adjusted length of the switching mechanism, the roller 58 is sprung around the end of the bar 60, thereby permitting the cam to ride out of the way of the the pins and allowing the sliding bar to return to its original ing the paper in any way.

If it is desired to avoid the necessity of withdrawing the sliding bar by a reverse turning of the handle, 1t may be retracted by a spring secured to the bar, or shaft and constantly tending to retract it. The feed shaft may accordingly have a pawl carrier 70 thereon (Figure 8), on which will be mounted a spring pawl 71, which pawl meshes with a ratchet 72, secured against the face of the driving pinion 45 of the feed. The pinion will in such a case be loose on the shaft instead of tight as illustrated in the first instance. The spring 73 will be held in a housing-74 mounted on the machine frame and also secured to the collar 75 of the gear 45. A pawl trip 76 located adjustably by a screw 7, engaging in a slot 78 thereof will trip the pawl, permitting a spring return at the desired point, dependent upon the feed adjustment.

It is believed that the operation of my various modifications will be evident from above without further remark, and that I have sufficiently indicated above that the fact of showing several of the modifications which occur to me is not to be taken as excluding other merely mechanical changes, which may occur to those skilled in the art in question.
